2-5 NL live hand

[brian4cards]

I have 66 in MP and there are a couple limpers in front of me. I raise to $25 and all fold except for one of the EP limpers. The flop is 8d 9d 6s. Checks to me, I bet $40 and am called. The turn is Ac. The guy bets $60, I raise to $225, he thinks and calls. The river is 5c, he thinks and checks. Should I check or push for my last $300? He has me covered.
